r.f.i.d for attedence register
I have actually wanted to work on a project using RFID. but unfortunely, I can't find any portable reader that can be able to operate more than 1 Meter. Unless, maybe U can try to get those very bulky active reader to help U.
The application of this active reader is frequently used in warehouse and logistic management. This was what I have read from my resources, after doing some research.
That is why, my project had became so complicated by adopting RFID concept but using a RF method.
